yet another "computer can't find phone" thread - T-Mobile LG G2x

this is the 3rd bricked g2x i've had and the others worked great. this one however isn't as easy.
here is what the phone does:
-power and volume down lets me in to cwm. i cleared and reset everything and tried to load a rom via sd but it keeps saying no files found.
-just power takes me to white lg then to blue lg and nothing else
-no battery and both volume buttons held, plugged into computer yields nothing.
i've tried numerous computers/drivers, as well as cables to no avail

nm. didn't notice until now that theres a small piece missing on the phone where the usb plugs in. wasn't making a good connection.
alls well now :good:

well the phone is having the same problem. it charges via usb to my computer but it doesn't come up as seeing it?
i know drivers are installed because it sees my g2x. and i know its not the cable cause again, it sees my phone with the same cable

It would help if you posted what ROM and and kernel you are running.

[Q] Phone not recognizing USB cord at all

I'm running Darky's 6.0 Rom with xcaliburinhand's kernel. I began to realize my phone wouldn't charge when I plugged it into the charger. I tried flashing to stock using odin but once I'd get into download mode via the long-press menu when pressing the power button (because other methods that involve plugging in the cord and pushing buttons doesn't work since it's not recognizing the cable). I don't think it's a faulty cable or port since everything was working before I flashed the ROM. Anyone have any ideas on how to get the computer to recognize the phone so I can flash stock??
edit: When I do plug in the phone to the computer, I'll sometimes get a message saying the device isn't recognized.
(And yes I do have drivers installed.)
Also, I tried flashing other ROMs via CWM but I get error messages on all that I try. Such as can't mount .dev/block/st19 and can't mount SYSTEM
Edit: After a while I've noticed that it in fact is charging but the battery icon doesn't show it's charging. And in settings it shows it's not charging. But battery level is increasing
Have you tried a different computer to see if the usb port is bad?
Sent from my SAMSUNG-SGH-I897 using XDA App
Does it charge when you plug it into an ac adapter? You can also try reinstalling the drivers and see if that helps and/or try a different usb port. I've had issues with the drivers before.
Also try a different cable. My cable became defective somehow where xp no longer recognized it, yet would still show charging on the phone. All was back to normal after I got another "data/sync" cable.
Sent from my SAMSUNG-SGH-I897 using XDA App
I don't have a different computer to try it on but I've tried different ports. It's not the computer because it still won't show it's charging when I plug into the wall. And yes I think it does charge when it's plugged into a wall but it doesn't show it or turn on when I plug the cord into the phone. I don't think it's hardware. It has to be software since it just happened when I flashed the ROM. Also whenever I open contacts I get a force close of acore (a little off-topic, but still another issue). I also have tried reinstalling drivers. But also, it doesn't work when plugged into a wall charger. So it's definitely nothing with the computer
I just need to know if anyone knows how to force the computer to recognize the phone so I can flash to stock and hopefully that'll resolve the issue
update: I also tried v7 via CWM and no luck still.
Well I update xcaliburinhand's kernel by transferring it over bluetooth and that installed fine over CWM. Then I tried updating Darky's rom to v7 and that worked too. I booted up and got a million FC's. Tried to get into recovery and it just sits at AT&T screen. It's very tricky to even boot up the phone, and even when I do I can't do anything because of all the Force closes. I can't get back into recovery mode with any button combinations and when i try via the power long press I can get into download mode fine, but I still have the issue with the computer not recognizing it, so it's useless. Anyone have any ideas????? I'm getting sick at staring at this AT&T boot screen for so long. I have no idea of what to do next. Someone please help!!
Sorry to say it, but it sounds like your phone has serious hardware problems.

Is there nothing I can do? Because I'm pretty sure I'm way past return date, and I didn't have a warranty.
well it sounds that you have messed it up. your installation is probably wrong somewhere, in fact i am even sure, but i dont want to hurt anybody.
do a clean install from scratch starting everything with ODIN (ie download mode)
first off all load a ancien but correct kernel, because in fact you don't even know what you lagfix is. load one of the zenkins kernels (ya-ok) no matter one of the recent ones.
start and go back into recovery, and adjust lagfix to ext4 only. not ext4/ext2
don't use not either the integrated voodoo.
it will format everything.
the again into recovery and disable lagfix
that will then reformat everything into rfs, that what it's needed.
then you go again into reboot and flash one of the ancien .tar files like xwjpa.
and then it shoudl startup.
and you can take it from there.

Unless you have a bad USB cable causing all the weirdness with both charging and the PC connection, but that wouldn't explain all the other strange errors. It sounds to me like the phone is terminally ill.

Doesn't there have to be a way to revert to stock if it's all because of the ROM? I really don't want to just give up and throw away a semi-new Captivate and have to break contract to buy another one.

I've seen no accounts of bad flashes causing problems like you described. Particularly the phone not being detected in download mode and the AC charging funkiness. Besides, you already tried reflashing it and not only did that not help, it revealed all sorts of other symptoms.

Ok. Thanks. If anyone else has any other ideas. Please post
I've had the Captivate for around 4 months. Does anyone know if I short out the phone and say it got really hot then shut off, they will exchange it?

TF not connecting to PC / Can't get into APX mode

Used Nvflash to root a while back ago. Worked flawlessly.
Started having problems where the TF was not connecting up to the PC (both laptop and desktop). No problems charging. I know there's something going on cause when I plug the TF into the USB port, the screen comes on. When I unplug it the screen comes on.
Thought it possibly was the the ROM (Prime 1.7). Wiped caches and re-installed. Nothing. Wiped data & caches and re-installed Prime 1.7 from scratch. Nothing. Wiped data & caches and installed Prime 1.6. Nothing.
Everything works fine other than I cannot get the TF connected (detected) on the PC and I cannot get into APX mode. I'm sure they're related. Did a search for not being able to get into APX mode and found a couple but no help.
I can get into recovery and see the tf in adb. Don't know what else I should be looking at.
[Update]
Just got the TF back from Asus. Missed it sooo much.
The ticket inside said they couldn't find any problems with it.
By the time the TF was off to Asus, I got my extra charger and cable. Tried the new usb cable and bam, device found. Most likely I was in APX mode but due to the cable, would have never known. The odd thing is the cable charges both the TF and the dock perfectly. All that for a f-n cable.
Now I'm fighting with Asus to replace my cable.
I hope this finds its way into others having the same issue.
Are you trying with a Linux machine or Windows?
Make sur you have all the required drivers installed for windows. APX requires additional ones....
On linux you will not see the device automatically when in APX but you can execute the nvflash script
Unfortunately I only have Windows machines.
When I press Volume Up + Power, I get nothing. It doesn't detect there's an APX device in my device manager for me to even install the drivers.
Also tired Volume Up + Volume Down + Power and nothing
Went back to total stock and I still can't get into APX mode and can't connect to the PC.
Talked to Asus support and they're stumped. Was told they had to research and get back to me.

This just happened to me. I booted HC then went to applications. Disabled/re-enabled USB debugging, then I went to device manager on windows and clicked "Scan for Hardware changes". It worked after that.
Tried that method as well.
Sent it off to Asus on a RMA. Crossing my fingers
Sent from my HTC Glacier using XDA Premium App
So this just randomly happens to me the day before I am supposed to sell it to someone. I went to nvflash it back to stock and noticed this issue. You said you restored it back to stock before you sent the RMA in, how did you go about doing so? I'd like to get it fixed so I can sell a functional unit.
Thanks
I'm also facing the same problem with my pc/laptop not detecting the TF101. The service center is of no help and they just give me the usual answers - try other pc, check the cable etc.
Moreover, I cannot go into recovery mode even with all the necessary drivers installed. Only a green droid with an exclamation mark.
I've no problem rooting the tf on older firmware. Wondering if the bootloader is locked.
I think it sounds like the usb cable as the op said it fixed his issue. I'm looking around for one to test on.
Sent from my DROID BIONIC using xda premium
Im on prime 1.7 and just experienced difficulty connecting, but can still charge. I just started the troubleshooting and found this thread. Disappointed, yet happy that its probably only the cable.
Well do you get any response from your computer? Anything, like a sound? a error installing drivers? a unknown device? Are you using the docking keyboard? Also this may not be the case but make sure you dont have a USB hub or anything extra on it. You can also try connecting it to the computer and open device manager and click scan for hardware changes. See if something new comes up. I have a couple more extensive ways of testing but let me know if this helps.

The new infuse drives me mad

Okay, to make it short, I've brought home a Samsung Infuse for testing. It's not even a day yet and it's showing one hell of a problem already. Firstly, I can't install the right drivers for it. I've used Kies and tried downloading every drivers I can find but no, the phone won't even connect as mass storage. I tried going into download mode by holding the volume keys and insert the usb cable but it only gets in download mode once every 20 tries or so, the other times it just boots right into the OS. In the rare cases of successful download mode, Odin won't recognize the phone. I used SGH-i997-UCKJ4-One-Click and finally it said the phone is connected, but intructed me to install the right drivers. So I did exactly as it said but the whole process of reinstalling drivers just repeats. I put the cm7 and mosaic ROMs in the phone using wifi and flashed them, here I met another problem, the phone keeps getting into car mode. I disabled it, and the phone changed orientation although I tried disabling it back and forth. I'm raging at it here, does anybody know about these problems or should I throw the infuse at the seller's face?

sounds like an issue with the usb port not the drivers.
try cleaning it, or you may need to send it to samsung for repair. if you dont want to do that then i'd make you an offer on it, but you might be insulted at what id pay for a "broken" device.
Something I ran in to as well, I ended up using the ports on the back of my PC.
Something else too ... I ended up using a Blackberry USB cable.
Hope this helps

Yea not an issue with infuse but the USB port. My laptop connects to it if I use the secondary or tertiary USB ports.

people read the whole post. his issue is not limited to computer connectivity. the phone goes into car mode on its own. car mode is triggered by a simple resistor in the car dock. different resistor values will put the phone in the different dock modes, Adam outler had a bunch on information on USB standards when he made his own captivate car mount. what is going on is most likely that a piece of semi conducive material is trapped in USB port on the phone or the port is otherwise damaged on the phone. there could also be some physical issue or calibration issue with the chip that controls the USB. I have seen similar issues on my own phone and seen atleast one post with issues identical to mine.
the seller sold it for a reason.

Sounds like PC to me, happens reboot PC and phone if it does not help I would suggest plugging it into another computer. If it works then try your computer again. This happened to me before with an external hard drive. Hope you get it worked out.
This also happened to me, it was working properly before but it just stopped. It seems that the phone always detects that there is a USB connected even if there was none, evidence is it is always in the charging state when I check the battery status. I think this is a hardware problem. I'm still looking for a solution for this.

I've never UNCHECKED USB Debugging.... during Odin connections or transferring files between phone and computer. As soon as I plug USB into phone, the USB symbol appears in notification bar and then I press notification to transfer files between computer and phone. My SR internal and external storage are recognized as drive letters on the PC. Try leaving USB Debugging checked and see if that works for you.

i highly believe this is a hardware problem because mine started when the phone overheat and turned itself off. I already tried resetting to factory setting but still the problem persisted.

good point there have been instances where I have had to switch ports to get it to work.
I remember also having the same problem with a USB cable I used with my captivate. This cable worked well with the captivate but when I plugged my Sky, I had the same problem as you. It took me a while to figure it out and change the cable.
Hope it help

Thank you.
Hey guys. I recently came across the same problem as the OP.
My phone will not detect that it is connected to a computer, and the computer will say that the device is not detected/has malfunctioned.
I have tried a factory reset, I have tried USB debugging, checking and unchecking, I have tried going into USB Storage and hitting the connect to PC button.
The phone does not connect using any of the 6 USB ports. It does not connect to my home or work computer. I have used two different cables, the stock and a third party one. (I have always used stock, never any third party until now to resolve this issue.)
This problem also came out of the blue, no changes were made. The phone is stock no rooting or flashing. Although that was the plan, but now it seems pointless.
Judging from the responses on many websites, I would have to say it's a software issue that can't be resolved. Or maybe a hardware issue. Either way I'm sending it into Rogers (Canadian carrier it originated from) tomorrow if I can't fix it by tonight.
I would love help from the outside public, but please respond with suggestions that are more intricate than to hit the connect to PC button, as I have exhausted all of those options already.
If this is a random occurrence, (and it seems like a common problem from all the results I get when searching for answers) then this phone model really needs to have a fix or something down the road soon, because this is ridiculous.
EDIT: Also tried reboot of the PC. It's Windows 7 64-bit so shouldn't need drivers either, and it was working fine last week.
If u did all that, u did ur due diligence in troubleshooting the problem. I almost guarantee ur mini-usb is dead, or maybe damaged so that it still allows charge but won't connect to computer. Send it in to Rogers, they should give u a temp phone in the mean time becuz its under warrantt
Yeah I figured something hardware related decided to crap out on me.
Is there a specific cause for this to happen? I plan on rooting and flashing different roms when I get the phone back, and don't want to have this happen again out of warranty, or else I'm screwed.
I try to take good care of my phone, so it's weird that this happened. If it is a common problem, then I guess I'd have to be careful to not do anything on my phone that's not reversible.

Replacing the usb port on some devices arent solving the issue.
For example, i have a usb bricked GT-N7000 and technician said that usb port is working on another device but there is something blocking usb mounting in the emmc. I dont have a bricked emmc, but the thing is i have been searching all over to find a fix for this thing more than a year now.

Phone will not connect as USB

I'm currently on Beans 13 rom and noticed that I cannot connect my phone to my computer via usb, all it will do it charge, I will not get a notification to use usb mass storage or anything like that. I uninstalled the drivers, rebooted my computer and phone, installed the drivers again and still does not give me the usb notification.
I then remembered that I did a nandroid on Beans 12 so I loaded that up and tried connecting to my computer and had the same exact issue. I took my phone to my roommate's laptop who also has a verizon S3 and tried connecting to his laptop. Still just charges, no notification.
I connected his S3 using the same exact cord to my computer and my computer recognizes his phone (although he is 100% stock).
I decided to try and Odin back to 100% stock. I loaded up Odin on my computer (Win 7 Pro 64 bit) and rebooted my computer into the odin/download mode and my computer/odin didn't recognize my phone. At this point I am at a lost. I have a suspicion that maybe the usb port on my phone went bad but in order to replace it with Verizon, I need to odin back to stock. Any one have any ideas?
I apologize if this has been covered before, I used the search and didn't see anything relating this.

I'm having the exact same problem with my GS3. The problem started after I flashed Beans B13 as well. I directly downloaded MDOB (it's a stock rooted ROM) and flashed it, but I am still having the issue. I haven't been able to figure it out either. Hopefully someone on here can help us out!
Well I think I solved the problem - at least for me. I tried the USB cable from my Dad's Droid X. Plugged the phone into the computer and everything works. No errors and the drivers installed correctly. I tried the cable that came with my phone (the one I have always used and has worked up until now) and it doesn't work. I get the error with it, but as soon as I use the one from the DX again, it works! Not sure why that is but I would say give it a try for sure! Let me know if it works for you too!
By the way, I got the idea from this thread:

Thanks for replying back! I meant to add a post. I got my phone working again. My roommate and I took apart the tip of my usb cable (the one that came with the phone) and noticed the green wire was broken off, so we soldered it back on and my phone was able to connect to my computer finally. Although it wasn't a strong connection and kept disconnecting.
For now I'm using a different cable from my hp touchpad and it's working perfectly fine so everything is all good now

That's good to hear! I guess both of our cables just went bad from use or something. Wish I would have tried another cable sooner instead of spending 4 hours installing and uninstalling drivers and wiping and installing ROMs over and over trying to solve the issue! :silly: But good thing we both figured it out! :victory:
I'm having the same problem as well...have now tried 4 different cables, hard reset, and every USB port on my machine and my buddy's computer to no avail. I verified the cables were 'good' on my buddy's gf's gs3 and it worked fine...just wont see mine. Charges just fine just no go on getting any data pass through it seems???
